M-375 Series

The NewTek M Series AC LVDTs are specially designed for applications demanding the highest levels of reliability while performing in the rugged environments that are required for industrial equipment. These transducers consist of a coil assembly potted into a 3/8” diameter housing with a separate moveable core. The M Series are available from ± 0.025 inch (± 0.63 mm) to ± 2.0 inch (±50 mm) and offer high sensitivity, high resolution and excellent linearity.
